Although fish oils may not be the first supplement that leaps to mind when you think of piling on muscle mass, experienced bodybuilders have long valued essential fatty acids (EFAs) for their unique combination of fitness-supporting benefits.

Celebrated for his insane workouts and magazine-cover-worthy physique, fitness icon Cory Gregory has recently taken his game to an entirely new level. In this exclusive ProSource interview, we talked to Cory about the value of settng (and writing down) new goals, his unusual new training regimen, and what it's like to reach your fitness peak at age 35.

For years, Beta Alanine has enjoyed a sterling reputation among hardcore bodybuilders who recognized and valued its central role in several processes of muscle growth and repair. The amino acid alanine, a primary transporter of nitrogen, is highly involved in protein synthesis, and is the primary glucogenic amino acid for the production of usable glucose from glycogen. Linked with histidine, it forms carnosine, a critical element in the muscle-building equation.

Lately, however, the good news about beta alanine has been accumulating at an astounding rate. A swiftly growing body of research indicates that beta alanine plays a much more critical role in anabolism than even its most dedicated users might have imagined. Specifically, beta alanine is emerging as a key agent in promoting significant increases in muscle carnosine, primarily by helping to buffer the effects of lactic acid. Fast-twitch muscle fibers, in particular, generally have high carnosine levels. As carnosine levels increase in muscle cells, they lead to a reduction in neuromuscular fatigue and consequent increases in muscle recovery and performance output.

In a recently published study(1), a series of experiments were conducted to assess beta alanine's effects on muscle carnosine levels. Researchers examined the effects of supplementing with 800 mg of beta-alanine given multiple times daily for four weeks on muscle carnosine levels. After 4 weeks of supplementation, muscle carnosine levels were significantly elevated by as much as 66%. This increased level of muscle carnosine was credited by the authors with a significant effect on intracellular buffering. In one of the first studies(2) to assess the combined effects of creatine monohydrate and beta-alanine supplementation, researchers randomized healthy men into four supplementation groups: placebo, creatine monohydrate only, beta-alanine only, and creatine monohydrate plus beta-alanine. Before and after 4 weeks of supplementation they all performed an exercise test that progressively increased in intensity while measures were made of their metabolic responses. The combined creatine and beta-alanine condition was the only group to demonstrate an increase in lactate threshold. This means that subjects in this group could exercise longer and at a higher intensity without accumulating toxic substances that can lead to fatigue. The findings provided preliminary evidence that creatine and beta-alanine may work together to produce favorable metabolic adaptations within skeletal muscle that translate into more efficient performance.

Additional work continues to be published on beta alanine, establishing it as a potent agent for increasing muscle buffering capacity through enhancement of muscle carnosine levels. Meanwhile, the remarkable effectiveness of this powerful amino has not escaped the researchers at ProSource. We were one of the first manufacturers to introduce a pure, premium-grade Beta Alanine.

When it comes to your workout regimen, better results are gained by way of increased performance. Work out longer, harder, and more productively with ProSource Beta Alanine!

Usage

Directions: Take one serving 20-30 minutes prior to workout, with juice or pre-workout drink, and one more serving sometime during the day. Take one serving twice daily on non-training days as well, with or without food. Begin with one-half serving twice daily to assess your tolerance as beta alanine may produce a slight and harmless flushing and/or prickly sensation that will subside within minutes of use.

Incredible preworkout supplement! I feel the tingle within 10 minutes and notice increased vascularity at the gym. Mental focus is at a high while on, no crash after.

(Posted on 6/6/2013)

First day I took it I began to feel tingly. I am real focused for my lift and it is great for recovery

(Posted on 6/3/2013)

Great stuff. I can really feel, it even when I take it by itself. I take it in conjunction with my pre-workout and my workouts and pumps are insane! I've been taking different pre-workout products for probably 8 years now and never combined it with beta-alanine. Love the feeling and mental focus I get throughout my whole workout. I did recommend this to a few of my gym buddies. Thanks prosource!

Great product - only complaint is the small bottle, hard to scoop it out of that little opening. Mix with PWO, great results. Love that Alanine tingle!

(Posted on 10/2/2012)

I stack this with Nitraflex before every workout. And it keeps me destroying the weights 6 days a week. Getting ready to order again. Great product!

(Posted on 7/29/2012)

great product. new bottle is terrible. unless u have extremely small hands u can not get product out of bottle after you have used about a third of it due to small opening.

(Posted on 6/24/2012)

Great stuff.

Great pricing for those on a tight budget!

(Posted on 5/10/2012)

Best bang for your buck. You can feel it start working within minutes

(Posted on 5/8/2012)

This is a great product to use pre and post workout. I will continue to use this supplement because it works.

(Posted on 4/28/2012)

A scoop of this with a scoop of BCAA in a cup of grape juice, makes the best pre workout drink for those of us on a tight budget, and I find it works just as well as any of those over hyped and pricey products out there

(Posted on 4/14/2012)

I have been using this for some time now and will stick with it. Only thing I can say is the product needs a longer handle on the scoup as it is hard to get your fingers in the narrow opening near the end of the product.

(Posted on 12/3/2011)

Simply amazing. I am in my late 40's, and work out at least 5 times per week. I would typically be very sore for the day or two after a workout, and it was really getting to me. I started taking this stuff, and the soreness is now almost completely gone! It does also seem that I can work out a bit harder, but I am only two weeks into taking it, so can't be sure on that. Regardless, based upon how much better I feel, this is now on my "must have" list. Great product!

I've just started using Beta-alanine with Synthatrex. This has been a good pre-workout for me

(Posted on 10/18/2011)

I just started using Beta-Alanine and BCAA's with just a little fruit juice and I find it to be a great pre-work cocktail. No jitters, just a smooth stream of energy that last my whole workout.

(Posted on 10/8/2011)

I've been using this Beta Alanine with BCAA's (put down with a carb drink) before my workout for about a year now, and I find it better then any preworkout supp that keeps you up at night and makes you sick or headache. This Prosource Beta Alanine is Excellent in effectiveness and quality.

(Posted on 9/27/2011)

I've been using this product for about 3 years now, and will use nothing else. I've gone through Black Powder, Yoked, Jack3d, etc. Nothing is as efficient, consistent, and cheap as this stuff. Doesn't keep you up at night, doesn't make you jittery... Doesn't require cycling... Cannot go wrong.

Great mass builder

(Posted on 8/22/2011)

Been taking this for about a week, it's freakin' great. Provides a great boost to my workouts. Taking it with WTF and makes me sweat like crazy. Read the bottle, makes your skin tingle - take a half a serving the first couple of times before going to the full scoop.

(Posted on 7/6/2011)

Excellent compliment to pre work out and pre bed time shakes. Low price, noticeable effects.

(Posted on 6/14/2011)

I add it to my preworkout drink even in my post recovery drink later in the day. It works very very well-- so does the price on such a tight budget.

(Posted on 4/21/2011)

The added endurance I get from this product is great. From pushing weights to swinging a bat. I can really feel the difference. Unbelievable price as well.

(Posted on 4/11/2011)

Beta Alanine is one of my favorite supplements, and I bargain shop everything I buy. ProSource has the best price & quality Beta Alanine on the net.

(Posted on 4/9/2011)
